Rx8 air on
« on: July 09, 2014, 05:02:59 PM »
My air conn isn\'t working

Looks like the acc magnetic clutch isn\'t operating due to a popped fuse. Swapped the fuse out and it popped right away....

Any ideas before I get the multi meter out?

Is there any known issues with the compressor clutch?

It will only pop a fuse with the ac on, current passes the fuse until it\'s switched on.

It\'s a 10a fuse, if you put a higher rated fuse in it looks to engage the clutch but no cold air comes thru.

You can turn the clutch by hand, which I assume means the compressor internals are moving?

Any ideas?

I would disconnect the plug to ac compressor (x19). Turn on ac.... fuse blows wiring or relay. If not then ac compressor. ohm resistance check of magnetic clutch. and socket where plug went into.

Page 68 of elec manual. Resistance check of magnetic coil.

I disconnected the plug and the fuse didn\'t pop.
.

Must be the clutch... I hope.

eBay is full of compressors on the cheap so will get one and try just swapping the mag clutch, if still having issues the. Will look at replacing the actual compressor and regarding :-(

Yes £20 delivered for a compressor with clutch.
 
Going to try to have off just the clutch from the replacement item and see how easy it is without a bearing puller.

Cool. Cheap as chips. Saves regassing as well.

Let\'s hope so.

Just had her re gassed at kiwi fit which cost nothing as it didn\'t fix the problem.

That\'s a good tip for everyone.

Unplug your compressor and take your car kwik fit... Regards... Not fixed? No charge... Plug in... Boom free regass lol

I know this is pikey but after they :censored::censored::censored::censored:ed my dad over with his service the other week they can suck it :-p

Compressor has arrived, really hoping it\'s just the coil from the clutch as I wouldn\'t trust swapping the compressor :-/

yep.. clutch and magnetic coil are just held in place with one bolt for the clutch, snap ring for the bearing and circlip for the magnet.

simple bit of WD40 and a rubber mallet to tap out the bearing and magnet :-)

al done fairly quickly on the spare sat on teh bench in the garage.. now the small matter of replicating teh process with the compressor still attached to the engine :-/
